Overview

The LPC1114FHN33/302,5 is an entry-level 32-bit ARM Cortex-M0 microcontroller designed for low-power, low-cost embedded applications. It features 32KB of flash memory, 8KB of SRAM, and a simple architecture intended to replace traditional 8-bit and 16-bit microcontrollers in high-volume designs. This variant is provided in a compact 33-pin HVQFN package suitable for space-constrained PCB layouts.

Why Choose This Part

This MCU offers a high code density with the ARM Thumb instruction set, reducing memory requirements compared to legacy architectures. Its deterministic interrupt handling and low gate count make it an efficient choice for real-time control tasks that require more processing power than an 8-bit MCU. The inclusion of a 10-bit ADC and multiple serial interfaces in a small footprint simplifies BOM integration.

Applications

System Supervisory Circuits
Managing power sequencing, reset logic, and system health monitoring in complex multi-rail designs.
Serial Protocol Bridge
Acting as a gateway between UART, I2C, and SPI peripherals to facilitate communication between different system ICs.
Consumer Peripheral Control
Controlling buttons, LEDs, and simple user interfaces in appliances and home electronics.
Sensor Hubs
Aggregating data from multiple analog or digital sensors before transmitting processed results to a primary application processor.

Getting Started

Development is supported by NXP MCUXpresso IDE as well as third-party toolchains like Keil MDK and IAR Embedded Workbench. Engineers can use the LPCXpresso development boards for rapid prototyping and link to the hardware via CMSIS-DAP or Segger J-Link debuggers. NXP provides the LPCOpen software libraries to jumpstart driver implementation for on-chip peripherals.
